The Budapest opera house is a beautiful Neo-Renaissance building opened in 1884. Construction included the use of marble and frescos by some of the best artisans of that era. Designed by Miklós Ybl, one of Europe's leading architects in the mid to late 19th century, the Budapest Opera House quickly became one of the most prestigious musical institutions in Europe. Many important artists performed here, including Gustav Mahler, who was also the director for three seasons.
The Budapest Opera House is considered to be amongst the best opera houses in the world in terms of its acoustics, and has an auditorium that seats 1200 people. It is horseshoe-shaped and, according to measurements done by a group of international engineers, has the third best acoustics amongst similar European venues (after the Scala in Milan and the Paris Opera House). The statue of Ferenc Erkel stands in front of the Opera House. He was the composer of the Hungarian national anthem and the first music director of the Opera. The other statue in front of the Budapest Opera is of Ferenc Liszt, the well-known Hungarian composer.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
